A strong emphasis on education, including technical and vocational training, also contribued to America's ecomonmic success, as did a willingness to experiment and to change .
did 的主语还是 emphasis.吗? 请教翻译? 谢谢.
是不是因为 AS 是连词, 所以必须引导一个从句,也就是说名词 willingness 必须要有一个动词. 这样一来, 主语就是 willingness了, 那后半句该怎么翻译好呢?
